Hmm, there is not /proc/fs/reiserfs on my system (?), but

debugreiserfs  /dev/mapper/exportraid-home  (yes, LVM)

tells me:

Reiserfs super block in block 16 on 0xfc00 of format 3.6 with standard journal

So I guess that's ok. Also note that the problems wer introduced onlt
after the latest kernel update while the filesystem was created a year
ago and running stable since that time!

I'm currently testing the patch against the acess/getattr flooding that
you sent here because a colleague who is running a few computer pools
observes a correlation between high nfs load and the stale NFS handles.

cu,
Frank
